CORS Usage in Controller

I do it like this for fonts for security you may need to do it different.

Code:

    # Add Font Types
    AddType application/vnd.ms-fontobject .eot
    AddType font/truetype .ttf
    AddType font/opentype .otf
    AddType font/opentype .woff
    AddType font/opentype .woff2
    AddType image/svg+xml .svg .svgz

    <FilesMatch ".(eot|ttf|otf|woff|woff2|svg|svgz)">
        Header set Access-Control-Allow-Origin "*"
    </FilesMatch>

You can read all about it from the link below.

Cross-Origin Resource Sharing (CORS)

what if I want to allow one controller to only abc.com and other controller to xyz.com?
